DEVICE FOR CUTTING MOLDINGS.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed July 23, 1906. Serial No. 327,447.

cutting moldings or strips of wood, has for its principal object to enable moldings or strips of wood to be cut equally and accurately and with great rapidity in the strip, at such places where moldings or strips of wood are united so as to produce a jointof the requisite angle corresponding to any of the geometrical figures for which moldings are used, for example a square, a hexagon, an octagon, as examples of figures or frames having an equal number of sides, and such as a triangle, pentagon, heptagon, nonagon or other figures or frames having an unequal number of sides. My invention also enables the use of a saw, chisel or other cutting instruments in forming the joining faces of moldings or other strips of wood to be entirely dispensed with, and produces the necessary cuts at a very rapid rate, thereby enabling moldings or other strips of wood to be put together in frame work with considerable saving of time as compared with existing methods.

The device constituting my invention is specially adapted for the use of picture-frame makers, cabinet makers, the manufacturers.

of doors, and door casings, window sashes and window casings, and other such work constructed by carpentry, for bein used in buildings, while it is generally app icable for cutting miter joints or joints of other angles than miter joints for use in wood work framing and molding generally.

My device consists of a pair ofjaws each having a handle and jointed together by a pivot upon which each jaw with its handle is movable both into the open and closed position, being by preference maintained when out of use in the open position by means of a.

spring fastened to one handle andp'ressing against the opposite handle as hereinafter described.

. Upon the annexed drawings Figure 1, is a plan of the device constituting my invention, showing it as it would appear when lying upon a picture framers, cabinet makers or carpenters or joiners bench when not in use. Fig. 2, is a side elevation corresponding to Fig. 1.. Fig. 3, is a plan of the upper part constituting the jaws and cutter of my said invention. Fig. 4;, represents a piece of molding in the straight, the inclined lines thereon showing the portion to be cut out forming a miter. Fig. 5, is another view of a similar piece of molding showing the part to ,be cut out, as actually cut out with the ends of the two outer parts of the molding each cut at an angle of forty-five degrees (45) so as to be placed together to form a miter joint. Fig. 6, is a plan of the two outer pieces of molding shown in Fig. 5, put together in the form of a miter joint.

In Figs. 1, 2, and 3, the jaw marked A, is that which carries the cutter B. The cutter B, is fastened into the jaw A, by a screw 0, shown in dotted lines in Figs. 1, and 2, and with the head of the screw shown in full lines in Figs. 2, and 3. The jaw marked D, is that which carries the piece of molding E, Figs. 1, and 3, to be cut so as to form a miter joint, indicated in Figs. 4, 5, and 6. The two jaws A, and D, are united operatively so as to move pivotally upon the pivotal screw .G, Figs. 1, and 2, by the pressure of the hand when drawing together the handles H, and I, respectively, into the closed position indicated by the dotted lines H, and I, in Fig. 1. When the handles H, and I, are closed by the pressure of the hand thereon into the positions H, and I, Fig. 1, then the jaws A, and D, are also closed and the miter cutter B, has made the miter cut J, shown at Fig. 4, so that the piece of straight molding is separated into the three portions K, L, and M, Fig. 5, while the two outer portions K, and M, are shown joined together in the form of one corner of the rectangular frame at Fig. 6. After the cutter B, has formed its cutting operation of the molding in the manner hereinbefore described, the hand of the user of the instrument constituting my invention is released from the handles H, and I, and the reaction of the spring N, causes the handles H, and I, also the jaws A, and D, to

open from their closed position marked H, and I, to their open position H, and I, and A, and D, shown at Fig. 1. wilt is explained that the cutter B, projects inwardly over the jaw D, as shown at Figs. 1, and 3, of a sufficient length to pass completely through the molding or other strip of timber and into the correspondingly shaped recess 0, in the jaw D. From this construction it follows not only that the molding or other strip of timber is completely supported at its back and bottom during the time the passage of the cutter B, takes place, but that the molding or other strip of timber E, is completely supported durin the whole time of the cutting action so t at the portion marked L, in Fig. 5, is completely severed from the other parts K, and M, with a perfectly square and smooth out throughout the severed surfaces, whereby the parts K, and M, fit accurately together and are ready to be fastened in their mitered position in a frame, door, or other article of wood work.

The rear face of the instrument constituting my invention is preferably fitted with a steel plug P, Figs. 1, 2, and 3, which is screwed tightly into the jaw A, and shown more especially at Fig. 1. This plug P, is shown at Fig. 2, with two pin wrench holes a, a, so that the plug Pfmay be tightly screwed into the jaw A, or the plug P, may

be formed flat sided andby means of a wrench screwed tightly into the hole in the j aw A.

The device constituting my invention may also be used as a wire twister or puller, or a nail remover by forming it with two semicircular recesses Z), Z), shown both by the lower and upper jaws at Fig. 1, and for other purposes of utility the lower end of the handle H, may be made as a nail or tack extractor, and the lower end of the jaw I, as a screw driver, but such parts, excepting in combination, do not constitute any part of my present invention.

It is to be understood that although I have in the annexed drawings shown the cutter B, in the formwhich will cut a miter or square joint, yet that when the joints form triangular, pentagonal, hexagonal, heptagonal, octagonal, nonagonal figures, or frames of any other number of sides are to be cut, then the angle of the two cutting edges of the cutter B, is made to correspond to whatever other angle of joint is or may be required.

For the purpose of insuring the right length of a piece of molding to be fitted into a frame of any of the kinds hereinbefore mentioned, and when or after two adjacent pieces of molding have been fitted into any of the frames hereinbefore mentioned, my in-.

strument is provided with a guide Q, projecting downward from the lower jaw D.

out a iece of molding or strip of wood to the Y exact ength to fit the space between the two adjacent pieces of molding already put together in a frame, this guide Q, is rested against the rabbet of the wood work by which the instrument is enabled to be held in the position for cutting the molding or strip to be placed in the rabbet, to the exact length required to fit the space whercinto it is to be placed.

Having now described the nature of my said invention, and the best system, mode or manner in or under which the same is or may be used or carried into practical efiect, I desire to observe in conclusion that what I consider to be novel and original and therefore claim as the invention to be secured to me by Letters Patent is as follows:
